Eibach 2.0 Pro truck shocks installed

New to the thread.
Just installed the Eibach 2.0 shocks in front and a 1.5 block in the rear.
Result:
FD height is 36, ground to fender.
DR height is 37.5 ground to fender.

After the install I’m getting a slight vibe in the rear. Did install a CB and it’s not as bad, but still feel it.

Would the vibe be from to much of a rake?
Looking for advice or recommendations. Should I raise the front or lower the back.

 

I started to get a little vibe after replacing my rear leaf packs so I did the CB drop and it went away. Also make sure you re-check the torque on everything after driving a bit. My u-bolts loosened up quite a bit. Also I might mention when measuring I was advised to measure from the fender to either the top or bottom of the rim so that tire pressure doesn't skew the measurements. Just my $.02

 

I checked the u bolts and they seemed tight. I’m thinking of raising the front a bit to help straighten out the driveline axle. didn’t want to go to much since I still have the stock UCA.

You are right about the measurements. I’ve read to measure from center cap to bottom of fender.
My Taco is a DCLB. Not sure how much that matters in keeping the truck sum what level for the driveline.

 

Did you install the ECGS bushing?

 

I did have that installed when I did the lift. I’m thinking if I can get it with less of a rake, that should resolve the slight vibe. Which I’ll raise the front a bit to level it out this weekend and hope the Eibach tool doesn’t break on me. Haha. I’ve read threads that the tool has broken from time to time.

 

Raising the front won't do anything to adjust the angle in the rear. The rear drive angle is a function of the your rear lift and is in relation to the back of your transfer case which is fixed. You could raise the front 20 inches but it does not impact the relative angles on your rear drive line. One thing to look at is an angled shim under your leaf pack which can help adjust your pinion angle which might be one reason you are getting a vibe.

 

I have adjusted mine a few times without problems. I just sprayed the threads and lifted the tires off the ground. Although like mentioned in the other reply raising the front probably won't help in this situation.

 

That wedge goes between the block and the axle?

 

Yup! that wedge or shim

 

Need a tapered block in the rear.

 

Just ordered a tapered 1.5” block. I’ll try that idea as well. Seems a bit easier than installing a shim from what I’ve seen.
Thanks
